Abstract

Cu2ZnSnSe4 thin films were prepared at 160~200 oC by spin-coating and chemical co-reduction, the effects of reaction temperature, time and substrates on thin films were investigated. Experimental results show that, the temperature, reaction time and process are the main factors that affect crystal phase and morphology of quaternary compound films. Longer reaction time and higher temperature are in favor of product crystallinity. Cu2ZnSnSe4 film with sigle phase and good crystallinity was obtained at 200 oC by twice reaction. Compared to the product films prepared on glass substrates, the crystallinity of Cu2ZnSnSe4 film on silicon substrates was slightly better.
